Selection Guide
Use the following criteria to confirm this module is the right choice for your application:
- Step 1 — Confirm PLC Platform: Verify your CPU is S7-200 SMART (not S7-200 classic or S7-1200)
- Step 2 — Count Output Channels: This module provides 2 analog output channels; if you need 4 channels, consider pairing two modules
- Step 3 — Verify Signal Type: Confirm whether your field device requires voltage (±10 V) or current (0–20 mA / 4–20 mA) input
- Step 4 — Check Load Impedance: Voltage output requires load ≥ 1 kΩ; current output requires load ≤ 500 Ω
- Step 5 — Count Total Expansion Slots: Ensure your CPU has an available expansion slot (max 6 modules per CPU)
- Step 6 — Confirm Power Budget: Add 1.5 W to your CPU power budget calculation

Replacement & Compatibility FAQ
Q: Can I use the 6ES7288-3AQ02-0AA0 with an S7-200 (classic) CPU?
A: No. The S7-200 SMART expansion bus is not electrically or mechanically compatible with the classic S7-200 series. You need the 6ES7232-series modules for classic S7-200.
Q: Can I use this module with an S7-1200 or S7-300?
A: No. This module is exclusively for the S7-200 SMART platform. S7-1200 uses its own signal board and expansion module range (6ES7 2xx-xxxx-0XB0).
Q: Is 4–20 mA output supported?
A: The hardware supports 0–20 mA. A 4–20 mA range can be configured in software by scaling the output value in STEP 7-Micro/WIN SMART.
Q: Can I mix analog input and analog output modules on the same CPU?
A: Yes. S7-200 SMART supports mixed expansion configurations. Analog input modules (e.g., 6ES7288-3AE04-0AA0) and analog output modules can be used simultaneously within the 6-module limit.
Q: What is the difference between 6ES7288-3AQ02-0AA0 and 6ES7288-3AQ04-0AA0?
A: The AQ02 provides 2 analog output channels; the AQ04 provides 4 channels. Both are S7-200 SMART compatible and use the same signal types.
Q: Do you provide a datasheet or wiring diagram?
A: Yes. Contact [email protected] and we will provide the official SIEMENS datasheet and wiring reference.
